Medical Physiology is the thoroughly revised, enlarged and updated edition of the textbook, now in full 4-color presentation. The four-color illustrations make the text not only attractive but more importantly help in the explanation of text much better than simple black-and-white illustrations. A large number of illustrations is new, giving more depth to the discussion of the topics. As in the previous editions, the fourth edition of the book has maintained its hallmark: Simplicity of presentation. Discussion on pathophysiological aspects in each chapter makes the understanding of physiology more relevant to the medical student. The text is completely clinically oriented, laying greater stress on the physiological concepts applicable in clinical situations.
